INFO: Could not find files for the given pattern(s). Codecamp Solidity Course

Question

I'm working on the free Solidity codecamp course. Around 3:58:44, we are trying to print a nonce. My error returns as "INFO: Could not find files for the given pattern(s). And then it says Traceback (most recent call last) etc, and throws a bunch of bytecode.

It should just return "0"

I'm completely new to coding, any help or directions would be appreciated.

from solcx import compile_standard, install_solc
import json
from web3 import Web3

with open("./SimpleStorage.sol", "r") as file:
    simple_storage_file = file.read()

# Compile Our Solidity

install_solc("0.6.0"),
compiled_sol = compile_standard(
    {
        "language": "Solidity",
        "sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
        "settings": {
            "outputSelection": {
                "*": {"*": ["abi", "metadata", "evm.bytecode", "evm.sourceMap"]}
            }
        },
    },
    solc_version="0.6.0",
)
with open("compiled_code.json", "w") as file:
    json.dump(compiled_sol, file)

# To deploy a contract, you need the bytecode and the ABI

# get bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["evm"]
["bytecode"]
["object"]

# get abi
abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]


# for connecting to ganache
w3 = Web3(Web3.HTTPProvider("http://127.0.0.1:7545"))
chaind_id = 5777
my_address = "0x16B7A2A9c869Fd89BAC5cD60CAf967C67d70F835"
private_key = "0x2f89f545fa407e76dc129908bb48a6ae457f88828c2f0a69b3737320a50b99f6"

# Create the contract in python
SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
# Get the latest transaction
nonce = w3.eth.getTransactionCount(my_address)
print(nonce)

Answer 1

• Make sure SimpleStorage.sol is in same directory as deploy.py.

Also I noticed that chainId is wrong. it should be 1337. 5777 is the network id for ganache.

    chain_id=1337
